PROCESS OF PRODUCING GAS.

SPECIFICATON forming part 4of Letters Patent No. 333,860, dated January 5, 1886.

Application filed April T, 1885. Serial No. 161,466. (No specimens.)

To @ZZ whom, it may concern,.-

Beit known that l', ERAZM. J. .TERZMAN- ovvsKi, ofthe city, county, and State of New York, have invented a new and useful Improvement in Processes of Producing Gas, of which the following is a full, true, and exact description, reference being had to the accompanying drawings.

The improved process which I shall proceed to describe is one in which the resulting gas is produced by the combined action of coal and lime upon steam and upon steam carrying petroleum or other hydrocarbon, as will be readily understood from the accompanying drawings.

The process consists, generally, in the use of two separate chambers, one containing lime and the other coal, by preference anthracite,

so connected that the products of combustion of the coal are used, by preference, with an additional supply of air in heating the lime to the requisite temperature for making the conversions hereinafter to be described, while the heated body of the coal and the lime unite together in producing the gas, which may or may not be afterward enriched in the well-known way. In order to accomplish this interaction of coal and lime, I cause steam to pass through the bodyof the coal, thereby making what is commonly known as watergas, and then unite with this an additional quantity of steam carrying a hydrocarbon in suspension. The said gas is caused to pass through a body of hot lime, thereby converting the steam and hydrocarboninto hydrogen, and, perhaps, a certain amount of carbonio acid, or carbonic acid and carbonio oxide.

In the accompanying drawings similar letters refer to similar parts.

Figure 1 is a vertical elevation o f my apparatus, and Fig. 2 is a top view of the same. Fig. 3 is a vertical elevation on the opposite side from Fig. 1. Fig. 4 is an end elevation showing some of the pipe-connections. Fig. 5 is a vertical transverse section through Fig. 1. Fig. 6 is a section through Fig. 2 on the lineyy, the position of the apparatus as shown, however, being reversed.

My apparatus consists, generally, in an external casing, A. Within this are two chambers, B and C. It is obvious that these chambers need not be in the same external structure, though I prefer to have them so for convenience and the saving of heat. These chambers are separated from each other by the partition L, except at the top of said partition, where they communicate with each other through the passage R. Each chamber may be provided with an upper opening at P P, as shown, which are suitably closed by means of sand seals. Through these openings the chambers are charged.

In the chamber B are likewise the openings b f, above the grate-bars S, whereby the chambers are readily discharged when desired.

In chamber N, beneath the grate-bars and beneath the chamber B, are ash-doors a and b. These doors are placed upon small chambers extending out somewhat from the main struc ture, and into their tops are the pipe-connections hereinafter to be described.

Beneath the grate-bars S of the chamber C are the doors c and g, for removing any lime which may fall through the grate-bars.

Toward the upper part of the chamber C, on one side are the open rings 7c k, communieating with the steam and naphtha pipe hereinafter to be described. In the opposite wall, likewise toward the top, are the openings g g, communicating with air-pipe F, hereinafter to be described. The chamber O,beneath the grate-bars S, communicates with the large pipe or chimney D. The upper end of this is closed by a suitable valve, E, which is controlled by a wheel and chain, p, as will be readily Seen.

Of course many other methods could be devised; but the one `shown is very convenient, for by it the valve when opened can be thrown completely out ofthe range of the escaping ases. The pipe J likewise communicates with the hydraulic main Il.

An air-pipe, F, is provided, through which air is forced by a blower or other suitable mechanism into the apparatus. This pipe has three branches, one communicating with the ashdoor h, one communicating with the ash-door a beneath the chamber B, and the other communicating with the openings gg in the lime-chamber C. A steam-pipe, G, is likewise provided. One branch of this enters the ash-chamber below the chamber B at IOO Z, as shown in Fig. 3. Another connection proceeds from this pipe G to the naphthainjectorK. Naphthaentersthisinjectorthrough the pipe r. The combined steam and naphn tha pass by the pipe H through the openings k k at the proper period of the operation.

Eye-holes m may be provided foronserving the internal condition oi' the apparatus. Suitable valves are provided in all these pipes and branches, which I will not here fully describe in detail,since they will be readily supplied by a competent gas-engineer.

The operation of my apparatus can now be readily understood. The chamber C is filled 0r partly iilled with lime in lumps by preference about three inches in diameter. A suitable supply of steam7 hydrocarbon, such as petroleum, and compressed air is provided. Instead of naphtha or petroleum, I may use some other liquid hvdrocarbon, or even a finely-divided solid hydrocarbon carried by a liquid or otherwise injected into the apparatus. I prefer, however, to use in this operation ordinary petroleum, which is both cheap and efiicacious.` The anthracite coal in chamber B having been kindled, air is allowed to enter through the branches of the pipe F, the quantity entering through the openings gg being by preference less than that entering through the openings a and h. The effect of this is to thoroughly heat the coal and lime, for the products of combustion pass upward through the coal-bed, and through the pas sage, R above the. lime, where they meet an additional supply of air, thereby completing the combustion. rIhe highlyheated gases then pass downward through the lime in the chamber C, through the chamber O, chimney D, pipe J, and thence escape through the purge-valve E, which is then open. When the lime has been heated to the proper temperature, the air-supply is cut off and the purge-val ve E closed. Steam and naphtha are then injected through the pipe H and openings k k. These, passing downward together through the linie-bed in the chamber C, become converted into an illuminatinggas of low candle-power, the candle-power depending in part upon the amount of petroleum added. At the same time, by preference, I cause a jet of steam to enter beneath the coalbed through the opening Z. This passes upward throughfthe coal-bed, and becomes converted into water-gas, and meets above the lime, steam, and petroleum there injected, and the combined water-gas, steam, and petroleum pass downward through the body of the lime. The resultant gas so produced is much superior in quality to watergas containing a much less percentage of carbonic oxide, and if the process is properly managed it is itself an illuminatinggas of several candlepower. This gas is subsequently enriched, if it is to be used as an illuminatinggas, by a hydrocarbon in the usual way. When the lime or coal has become so much cooled by this action as to cease to act efficaciously, the steam and naphtha are shut oft", and air is again admitted.

By means of the alternate doors above the grate-bars the apparatus is readily discharged in case of need, and the supply of coal and lime is readily kept up through the openings above.

The apparatus is complete and convenient, and is not liable to injury or destruction.

I do not in this application claim the apparatus, as I intend to make a separate application therefor.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. The process herein described of making a combustible gas, which consists in rst making water-gas by injecting steam through an incandescent body ot' carbon, in then adding to said water-gas steam and hydrocarbon, and in passing the combined water-gas. steam, and hydrocarbon through a converting body of heated lime, substantially as described.

2. The process herein described of makingv a combustible gas, which consists in rst making watergas by injecting steam through an incandescent body et" carbon, in then adding to said water-gas steam and hydrocarbon, and in passing the combined watergas, steam, and hydrocarbon through a converting body of heated lime, and alternately heating the lime by the products of combustion of the carbon used in making the water-gas, substantially as described.

3. The mode of producing a combustible gas, consisting in combining hydrocarbon and steam with a water-gas, and then subjecting the said gas, steam, and hydrocarbon tothe action of heated lime, substantially as de. scribed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
